Honest PC security. Defender, done right.
A real Security Center built on the antivirus you already trust — Microsoft Defender. We ship no second engine and no signatures of our own; we drive the Defender that's already in Windows. Add a native persistence audit and system-wide ad, tracker & malware blocking by DNS. No scareware. No fake counts. Every hardening toggle can be switched back.
A Security Center built on Microsoft Defender
See your live protection at a glance and control it in one click — without a second antivirus fighting the first.
Most "security suites" install a whole new engine that elbows Defender out of the way, then sell you a subscription to fix the gap they created. We went the other direction. The Security Center is an honest wrapper over the Defender already in Windows. It shows your live protection posture — real-time protection, definition age and version, last quick and full scan, tamper protection, behaviour monitoring — and lets you run Defender Quick, Full or Folder scans in a click, with real threat history and Defender's quarantine list. Restoring a quarantined file stays in Windows Security, where the detection details sit next to the decision — that is not a call an optimizer should be taking for you.
Live protection posture
Real-time status, definition age, last scan, tamper protection and behaviour monitoring — read straight from Defender. If a read fails it says "status unavailable", never a fake "unprotected".
Scan in a click
Quick, Full or Folder scans, driven through Defender's own engine. Full scans auto-pause while a game or emulator is running. We do not offer a definition-update button — Windows Update already delivers those several times a day.
Real threats, real quarantine
Your actual threat history and Defender's quarantine list, read straight from Defender. Restoring an item is done in Windows Security. No invented threat counts, no "47 issues found" scare screen.
5 reversible hardening toggles
Cloud-delivered protection, automatic sample submission, block PUA, Controlled Folder Access and Network Protection. CFA and Network Protection start in safe Audit mode — log only, block nothing. Each remembers its prior value so Undo is exact.
System Integrity Audit — a true persistence audit
The Integrity Audit scans the places malware actually hides — using only files and metadata.
A true persistence audit. It scans WMI persistence, IFEO hijacks, rogue scheduled tasks, hosts/proxy redirects and fake system processes — using only files-at-rest and WMI metadata. No engine, no driver, no injection. It never reads a game's live memory and never calls OpenProcess into an anti-cheat. Findings are ranked by severity and confidence.
10 checks for where malware persists
Metadata only — no engine, no signatures, no driver. Each finding is ranked by severity and confidence:
Block ads, trackers & malware — with DNS, not a hosts hack
System-wide blocking for every browser and every app, plus 16 reversible Windows privacy switches.
Block ad, tracker and malware domains across your whole PC — every browser, every app — by switching to a filtering DNS resolver. No browser extension required. An optional adult-content category switches to AdGuard Family DNS, which adds adult-content blocking and SafeSearch. It lives in the Privacy Center, alongside a separate encrypted-DNS (DoH) toggle and 16 reversible Windows privacy and telemetry switches.
DNS ad, tracker & malware blocking
Point your active adapter at a filtering resolver to block ad, tracker and malware domains everywhere — no extension. An optional category adds adult-content blocking and SafeSearch via AdGuard Family DNS.
Encrypted DNS (DoH)
A separate one-tap toggle for DNS-over-HTTPS, so your lookups can't be read or tampered with on the wire.
16 privacy switches
Sixteen reversible Windows privacy and telemetry toggles, grouped General / Telemetry / Tracking & ads / Windows AI — including Windows Recall (AI snapshots) blocking and Edge telemetry. Each reverts to the captured Windows default.
Protected DNS rollback
We snapshot and validate real IP addresses, never disable the Windows DNS Client service, and restore the captured configuration only after re-parsing it. If the protected backup is invalid, rollback safely returns the adapter to automatic DNS.
Two buttons on the dashboard. Both honest.
A safe pass for everyone, and an explicit aggressive pass when you know what you're trading.
Smart Optimize selects the modules matched to your hardware tier, and confirms how many of them are flagged Caution before it runs. It does not silently change privacy or Windows security. System-wide changes—including VBS/HVCI or Spectre mitigation controls—are explicit Caution or Advanced actions with their security and restart costs shown first.
Your security questions, answered straight
Does this replace my antivirus?
No. The Security Center is an honest wrapper over Microsoft Defender — the antivirus already in Windows. It ships no second engine and no signatures of its own; it drives the Defender you already trust. It never registers itself as a Security Center AV, because that would silently disable Defender, and there is no "disable Defender" button.
Will the Integrity Audit flag my games or anti-cheat?
No. BattlEye, EAC, Riot vgk/vgc, FACEIT, nProtect, mhyprot and emulator/GameLoop components are allow-listed before anything is surfaced. The scan uses only files-at-rest and WMI metadata — no engine, no driver, no injection — and never reads a game's live memory. It's a persistence audit, not real-time antivirus.
Does the ad blocker edit my hosts file?
No. It's filtering DNS — it points your active adapter at AdGuard's public resolver. There's no giant hosts-file blocklist to choke Windows DNS, nothing for antivirus to lock. We snapshot your real DNS first, only flush (never disable) the Windows DNS Client service, and turning it off is protected DNS rollback that restores the DNS settings you had before.
Is all of this free?
Yes. The Security Center, Integrity Audit, DNS blocking and the 16 privacy switches are all free. Pro adds two Guardian auto-maintenance engines: an idle Defender quick scan, and a daily persistence-baseline diff that alerts only on new items.
Can I undo a change I don't like?
Yes. Every Defender hardening toggle and most Integrity Audit fixes ride the same signed-backup Undo as the optimizer modules and restore the exact prior value. Risky items like root-cert removal are detect-only with guidance. DNS blocking is protected DNS rollback, and every privacy switch reverts to the Windows default. More in the FAQ and on the safety page.
Everything in Pro, plus Smart Route
The same honesty rules extend to your connection: the game relay measures your real path and only reroutes when it genuinely beats your ISP, stays direct when it can't help. $9.99 (charged as ₹899)/year, renews yearly until you cancel; measuring your route stays free for everyone.
Honest security, no scareware
A real view of Defender, a true persistence audit, and system-wide ad and tracker blocking by DNS — all free, rollback-supported where applicable. No second engine. No fake counts. No hosts-file hack.
